Abstract

A plate-type heat exchanger, in particular for motor vehicles, is provided that includes a plurality of plate groups in order to form first and second and/or third flow paths, a spatial region for fourth flow paths being formed between adjacent plate groups, the plate groups having at least one plate pair having a first and second plate in order to form the first flow paths and the second flow paths, wherein a third plate can be arranged in interaction with one of the first or one of the second plates in order to form the third flow path.

First claim

What is claimed is:

1. A plate-type heat exchanger for motor vehicles, the heat exchanger comprising:
a plurality of plate groups to form first, second and third flow paths, wherein a spatial region for a fourth flow path is formed between adjacent plate groups, each plate group having at least one plate pair having a first and second plate to form the first flow path and the second flow path; and
a third plate arranged in conjunction with one of the first or one of the second plates in order to form the third flow path,
wherein the third plate has, at each of two opposite end regions thereof along a longitudinal direction, a single cup projecting therefrom, such that the third plate only includes a total of two cups, the two cups being a first cup provided at a first one of the two opposite end regions of the third plate and a second cup provided at a second one of the two opposite end regions of the third plate, the first cup and the second cup of the third plate each connecting solely to the third flow path,
wherein the first plate has three connecting regions at each of two opposite end regions along the longitudinal direction, such that in each of the two opposite end regions, a first one of the three connecting regions acts as an inlet or outlet of the first flow path, a second one of the three connecting regions acts as an inlet or outlet of the second flow path and a third one of the three connecting regions connects to the third flow path, wherein the first plate further includes two channel-forming structures between each of the two opposite end regions to form the first and second flow path,
wherein the second plate has three connecting regions at each of two opposite end regions along the longitudinal direction, such that in each of the two opposite end regions, a first one of the three connecting regions acts as an inlet or outlet of the first flow path, a second one of the three connecting regions acts as an inlet or outlet of the second flow path and a third one of the three connecting regions connects to the third flow path, wherein the second plate further includes a channel-forming structure between the two opposite end regions to form the first flow path,
wherein the third plate is narrower than each of the first plate and the second plate, and
wherein the second plate is sandwiched between the first plate and the third plate.

2. The heat exchanger according to claim 1 , wherein a volume of the second flow path is smaller than a volume of the first flow path.

3. The heat exchanger according to claim 1 , wherein the third plate is connected to the second plate such that the third plate is arranged in a plate region of the second plate without a channel-forming structure or with a modified or reduced channel-forming structure and forms the third flow path, wherein the first cup of the third plate communicates with the third one of the three connecting regions at a first end region of the two opposite end regions of the second plate and wherein the second cup of the third plate communicates with the third one of the three connecting regions at a second end region of the two opposite end regions of the second plate.

4. The heat exchanger according to claim 1 , wherein in each of the two opposite end regions of each of the first plate and the second plate, the first one, the second one and the third one of the three connecting regions are arranged next to one another.

5. The heat exchanger according to claim 1 , wherein in each of the two opposite end regions of each of the first plate and the second plate, the third one of the three connecting regions is arranged between the first one and the second one of the three connecting regions.

6. The heat exchanger according to claim 1 , wherein in each of the two opposite end regions of each of the first plate and the second plate, the third one of the three connecting regions is arranged next to the first one and the second one of the three connecting regions.

7. The heat exchanger according to claim 1 , wherein the first one and the second one of the three connecting regions at each of the two opposite end regions of the first and second plate are formed as cups, and the channel-forming structures of the first and second plate and a channel-forming structure of the third plate are made equally deep in a direction perpendicular to a plane of the first, second or third plate.

8. The heat exchanger according to claim 1 , wherein the first one and the second one of the three connecting regions at each of the two opposite end regions of the first and second plate are formed as cups, and the channel-forming structures of the first and second plate and a channel-forming structure of the third plate are formed in a direction perpendicular to a plane of the first, second or third plate, and wherein a depth of the channel-forming structures of the first plate is greater or smaller than a depth of the channel-forming structures of the second and third plate.

9. The heat exchanger according to claim 1 , wherein the first one and the second one of the three connecting regions at each of the two opposite end regions of the first plate are each formed as a respective cup, and wherein the third one of the three connecting regions provided at each of the two opposite end regions of the first plate for connection to the third flow path is an opening, such that the first plate only includes a total of four cups.

10. The heat exchanger according to claim 9 , wherein the four cups of the first plate project in a direction that is opposite to a projecting direction of the two cups of the third plate.

11. The heat exchanger according to claim 1 , wherein the first one and the second one of the three connecting regions at each of the two opposite end regions of the second plate are each formed as a respective cup, and wherein the third one of the three connecting regions provided at each of the two opposite end regions of the second plate for connection to the third flow path is an opening, such that the second plate only includes a total of four cups.

12. The heat exchanger according to claim 11 , wherein the four cups of the second plate project in a same direction as a projecting direction of the two cups of the third plate.

13. The heat exchanger according to claim 9 , wherein the two cups of the third plate each have a greater depth than a depth of each of the four cups of the first plate.

14. The heat exchanger according to claim 1 ,
wherein the first one, the second one and the third one of the three connecting regions at each of the two opposite end regions of the first plate are each formed of a separate, respective opening, such that three openings are provided at a first one of the two opposite end regions of the first plate and three openings are provided at a second one of the two opposite end regions of the first plate, and
wherein the first one, the second one and the third one of the three connecting regions at each of the two opposite end regions of the second plate are each formed of a separate, respective opening, such that three openings are provided at a first one of the two opposite end regions of the second plate and three openings are provided at a second one of the two opposite end regions of the second plate.
